Lake Balboa
Trusted home addition contractor in Thousand Oaks. Construction by Maya builds seamless room additions that expand your living space while maintaining architectural harmony, comfort and flow.
Families outgrow Thousand Oaks homes for predictable reasons. A third bedroom that was never quite enough, a primary suite built to 1970s expectations, or a family room that cannot hold everyone at once. Moving solves it. So does adding on, usually for less, and without leaving a neighborhood you chose deliberately.
Founder Hila Hemo leads our boutique team with a listening-first approach. First, we work out where the space can actually come from. Then our licensed team handles engineering, permits and construction. Finally, the new rooms read as though they were always there.
We tailor every room addition in Thousand Oaks to your home and your plans. Moreover, we bring every trade under one roof. So your project runs with one team and one clear plan, from a single bedroom to a full second story.
Extra bedrooms for growing families or guests. Designed to flow naturally from your existing floor plan.
A private retreat with a spa-like bath and walk-in closet. The most requested addition we build.
Open, light-filled living space for gathering and entertaining. Connected seamlessly to your kitchen.
Double your footprint without losing yard space. Fully engineered and built to match your home.
Comfortable, private space for parents or long-term guests. Complete with bath and kitchenette options.
Push a wall out and gain the island, pantry or dining nook your kitchen always needed.
Before anyone draws anything, the useful question is which direction your house can grow. Thousand Oaks properties usually offer more than one answer, and they carry very different price tags.
Most contractors will not discuss numbers until they have walked your home. We think that wastes your time. Below are the ranges we typically see for Thousand Oaks and Conejo Valley additions, with realistic timelines from permits to final walkthrough.
| Addition Type | Typical Investment | Timeline With Permits | What Drives The Range |
|---|---|---|---|
| Bump-Out, 50 to 150 sq ft | $40,000 - $90,000 | 2 to 4 months | Foundation work, roof tie-in and whether plumbing or HVAC extends |
| Bedroom Addition, 200 to 400 sq ft | $90,000 - $180,000 | 3 to 5 months | Size, closet and bath inclusion, and how the new roofline meets the old |
| Family Room Extension | $120,000 - $240,000 | 4 to 6 months | Span width, structural beams, glazing and connection to the kitchen |
| Primary Suite, 300 to 600 sq ft | $140,000 - $290,000 | 4 to 7 months | Bathroom finish level, walk-in closet build-out and exterior materials |
| In-Law Suite With Kitchenette | $180,000 - $350,000 | 5 to 9 months | Separate entrance, second kitchen rough-in and panel capacity |
| Second Story, 600 to 1,200 sq ft | $300,000 - $600,000+ | 8 to 14 months | Foundation and shear upgrades, new stair, full reroof and temporary weather protection |
These ranges reflect typical Thousand Oaks and Conejo Valley additions. They are a planning guide, not a quote, and they exclude city impact fees, which vary. After we walk your home, you receive a written, itemized price with no hidden allowances.
Our room addition process in Thousand Oaks stays simple, transparent and collaborative. First, we listen. Then, we plan every detail with you. Because of this, you feel confident from the first call to the final reveal.
First, we meet at your Thousand Oaks home. We review your space, goals and budget together.
Next, we design the addition and secure engineering and permits. You get realistic timelines and clear pricing in writing.
Then our crew builds with precision. Meanwhile, you receive regular progress updates and a clean job site.
Finally, we complete a careful walkthrough and final inspections. Your new space is ready to enjoy.
An addition here has to clear three separate tests. It must fit within setbacks and lot coverage. It must respect protected oaks, whose root zones reach well past the canopy and frequently limit exactly the rear yard where you wanted to build. And it must look like it belongs, both to your HOA and to anyone driving past.
We work all three at design stage rather than discovering them at plan check. Consequently the footprint we draw is one that can actually be built, and the exterior we specify blends rather than announces itself.
Tree, hillside and zoning requirements vary by parcel and are updated periodically. We confirm the current rules for your property during your free consultation.
Send us your address and what you are missing. We will tell you which routes your lot actually supports and roughly what each one costs, before you call a realtor.

Photos say more than any promise. Here is a look at recent addition, ADU and interior work from our team across the Conejo Valley and greater Los Angeles.
A home addition opens up endless possibilities. For example, you can add a primary suite, a bigger family room or a home office that finally fits. From foundation to matching rooflines, our team turns more space into more life for Thousand Oaks families.
There is no shortage of addition contractors in the Conejo Valley. Here is what makes working with a small, owner-run builder different.
Matching stucco texture, roof pitch and window proportion is the difference between an addition and an obvious bolt-on. We specify those details before framing, not after.
Where a lot supports both an addition off the back and a second story, we cost both. Consequently you choose direction with real figures rather than a preference.
Structural calculations, beams and foundation design are handled in-house. Therefore you are not coordinating an architect, an engineer and a builder who blame each other.
Hila and Moses are on your project through a build that can run half a year. The person who quotes your addition answers your call in month five.
Most addition work happens outside your existing walls, so we open the connection late. Consequently, daily disruption stays low through the majority of the build.
License #1034501, general liability and workers compensation on every job. In addition, we provide current certificates before work starts, without you having to ask twice.
Our reputation rests on trust and care. Above all, we deliver on our promises. So read what homeowners across Thousand Oaks, Calabasas and the Conejo Valley say about building with our team.
An addition changes your home permanently. The projects that go smoothly are the ones where these six things were settled before design started. We work through all of them with you at no cost.
Worth pricing honestly. Between agent fees, transfer costs and current rates, staying and building is often the cheaper path. We will tell you if we think moving wins.
Protected oaks shape where an addition can go, and their root zones reach further than most people expect. That answer often decides direction on its own.
The point where new meets old decides how the whole house flows afterward. A well-placed addition improves the existing rooms. A poorly placed one creates a hallway to nowhere.
New square footage needs conditioned air. Sometimes the existing system stretches. Often it cannot, and that upgrade belongs in the budget from day one.
If you are staying twenty years, build what you want. If you may sell in five, we steer you away from anything that overbuilds the street or narrows your buyer pool.
Tell us the budget you actually have, not the one you think we want to hear. Then we design to it honestly, instead of value-engineering under pressure later.
